Ngaire - welcome back - sounds like you might have visited the same house - or group of houses - where we saw the guinea pigs - in Ollyantambo? We bought a lovely weaving from the ladies at Chincero.
One couple on our trip took a side trip for chicha tasting - she is a food historian, writer and instructor at the Culinary Institute and was quite keen on trying it, but didn't have anything positive to say about it!
Look forward to seeing Ken's pictures.
